Hi all reefers, I just setup my nano tank 1-2 months ago. However, the zoas in my tank is really in a bad shape. Is it coz of low lighting??? Need help! Also, my orange sponge is losing colour, which I think it's becoz it has been exposed to air both by the shop owner and me:(
Tank specs:
31x31x36cm
Pump: 480L per h
22 LED bulbs
5.2W
